Crumbuino-Nano ATmega328 Module (Arduino-compatible)

Crumbuino-Nano - Arduino compatible Atmel AVR ATmega328 microcontroller module with USB UART.


Crumbuino-Nano corresponds to our popular Crumb328 V2.3 module with the ATmega328P mikrocontroller and CP2102 USB UART converter. As Crumbuino-Nano version the module comes with Arduino bootloader preloaded and separate 16MHz crystal. In this configuration it is comparable to Arduino Nano V3.0 module!

Due to the preloaded Arduino Bootloader and the integrated USB UART converter with mini-USB connector, the module can directly be used with the Arduino IDE. The corresponding board support package (BSP) is available here: https://github.com/beegee-tokyo/Crumbuino-Chip45. Alternatively is can be used as Arduino Nanoboard.

Main differences to the Arduino Nano V3.0 is a different pinout, no 5V regulator (the Crumbuino-Nano can be supplied through USB) and the status LED is connected to a different pin.

You can find further information in the Infosheet.
